Feminists and women who don't like pain have reason to celebrate, but here's another group that should embrace the natural trend: doctors. American society's aestheticization of hairless female genitalia apparently came at the cost of a veritable epidemic of grooming-related injuries. And while the Brazilian trend got lots of attention, the attendant carnage did not. Luckily, a team of doctors led by Allison Glass of the University of California, San Francisco, was on the case. For a 2012 paper in the journal Urology, theyanalyzed Emergency Room data on relevant injuries caused by pubic hair grooming related injuries and found:

"Between 2002 and 2010, the number of injuries increased fivefold.

Of the cohort, 56.7 percent were women. The most at-risk group was women aged 19 to 28.

Shaving razors were implicated in 83% of the injuries.

Laceration was the most common type of injury (36.6 percent).

The most common site of injury was the external female genitalia (36 percent).
